Tests of proportional hazards and proportional odds models for grouped survival data
(International Biometric Soc, 2014)
Mortality in parenchymal and subarachnoid neurocysticercosis
(American Society of Tropical Medicine and Hygiene, 2021)
Neurocysticercosis (NCC) is endemic in many parts of the world, carrying significant neurological morbidity that varies according to whether lesions are located inside the cerebral parenchyma or in extraparenchymal spaces. ...
Economic conditions and birth spacing in Colombia: a semi-parametric approach
This document aims to provide evidence on the association between economic conditions and household fertility decisions related
to birth spacing by using a Cox proportional hazards model. The contribution of the paper is ...
Properties and inference for proportional hazard models
(Universidad Nacional de Colombia, 2013)
We consider an arbitrary continuous cumulative distribution functionF(x) with a probability density function f(x) = dF(x)=dx and hazard functionhf (x) = f(x)=[1
In peru, reporting male sex partners imparts significant risk of incident HIV/sexually transmitted infection: All men engaging in same-sex behavior need prevention services
(Wolters Kluwer Health, 2013)
Background: Detailed information on the sexual behavior of bisexual, non–gay-identified men and the relationship between same-sex behavior and HIV/sexually transmitted infection (STI) incidence is limited. This study ...
A semi-Markov multistate model for estimation of the mean quality-adjusted survival for non-progressive processes
(SPRINGER, 2009)
We discuss the estimation of the expected value of the quality-adjusted survival, based on multistate models. We generalize an earlier work, considering the sojourn times in health states are not identically distributed, ...
Estimation of the mean quality-adjusted survival using a multistate model for the sojourn times
(ELSEVIER SCIENCE BV, 2008)
In clinical trials, it may be of interest taking into account physical and emotional well-being in addition to survival when comparing treatments. Quality-adjusted survival time has the advantage of incorporating information ...
Modelo logístico generalizado dependente do tempo com fragilidade
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2011-02-11)
Several authors have preferred to model survival data in the presence of covariates through the hazard function, a fact related to its interpretation. The hazard function describes as the instantaneous average of failure ...
